“…Conventional techniques like adsorption [1], absorption [2,3], condensation [4,5], catalytic oxidation [6,7], photocatalysis [8][9][10], membrane purification [11] and biological treatment [12,13] which have been used for removal of VOCs have disadvantages such as low efficiency and high energy consumption. The merits and demerits of various technologies available for the abatement of VOCs are reviewed in the work by khan et al [14], Parmar et al [15] and Luengas et al [16].…”

Non thermal plasma (NTP) reactors packed with non-catalytic or catalytic packing material have been widely used for the abatement of volatile organic compounds such as toluene, benzene, etc. Packed bed reactors are single stage reactors where the packing material is placed directly in the plasma discharge region. The presence of packing material can alter the physical (such as discharge characteristics, power consumption, etc.) and chemical characteristics (oxidation and destruction pathway, formation of by-products, etc.) of the reactor. Thus, packed bed reactors can overcome the disadvantages of NTP reactors for abatement of volatile organic compounds (VOCs) such as lower energy efficiency and formation of unwanted toxic by-products. This paper aims at reviewing the effect of different packing materials on the abatement of different aliphatic, aromatic and chlorinated volatile organic compounds.

“…Mou et al [166] used tripodal tridentate copper complex containing mesoporous silica to efficiently activate the methylbenzene aliphatic C-H bond and synthesize the benzyl alcohol, and benzaldehyde. Moreover, the total oxidation removal of methylbenzene could be obtained over the various metals modified mesoporous silica such as Co-MCM-41 [167], Cu-MCM-41/SBA-15 [168,169], Mn-SBA-15 [170], Fe-Ti-MCM-41 [171], Cu-Mn-MCM-14 [169], etc. Furthermore, the further oxidation of benzyl alcohol has also been noticed using the transition metal-based mesoporous silica.…”

Ordered mesoporous silicas (OMSs) attract considerable attention due to their advanced structural properties. However, for the pristine silica materials, the inert property greatly inhibits their catalytic applications. Thus, to contribute to the versatile surface of OMSs, different metal active sites, including acidic/basic sites and redox sites, have been introduced into specific locations (mesoporous channels and framework) of OMSs and the metal-functionalized ordered mesoporous silicas (MOMSs) show great potential in the catalytic applications. In this review, we first present the categories of metal active sites. Then, the synthesized processes of MOMSs are thoroughly discussed, in which the metal active sites would be introduced with the assistance of organic groups into the specific locations of OMSs. In addition, the structural morphologies of OMSs are elaborated and the catalytic applications of MOMSs in the oxidation of aromatic compounds are illustrated in detail. Finally, the prospects for the future development in this field are proposed.

“…In recent years, SBA-15 and its modified have attracted more and more attention as a promising material in chemical engineering and environmental science because of the large surface area, large pore size and high stability [29,30]. Herein, in this work, a series of Ag, Mn and AgMn loaded SBA-15 samples were prepared using an impregnation method and both their adsorption capacity and catalytic performances were evaluated.…”
